To all "whom it may concern:

Be it known that I, JACOB K. VON GAL, a citizen of the United States, residing at Danbury, county of Fairfield, State of Connecti- 5 out, have invent-ed an Improvement in Processes of Dyeing Opalescent and Fluorescent Effects on ool and Fur Felt, of

which the following is a specification.

This invention relates to the treatment of felt either wool or fur felt whereby changeable efiects,as opalescent and fluorescent effects, may be obtained.

In carrying out the invention the body of the felt is formed from wool or fur all the same color, or after the felt is made it may be dyed either all the way through of a given color, or may be dyed of a given color to a considerable depth from the surface. Then the surface is dyed with a difierent color! or shade which should be superficial. that is, should not penetrate the body of the felt to any appreciable extent. The surface is then cut or broken by suitable means such as sand paper, a wire card or heavy bristle brush, so that the body color shows through and mingles with the surface color. By varying the amount of the cutting or breaking operation any desired effects may be secured, that is, by cutting or breaking the surface only slightly, the surface color or shade will predominate, while if carried deeper the two colors or shades may be made to be substantially equally prominent, while if carried still deeper the body color or shade may be made to predominate.

. By way of a specific example, which is merely illustrative, we will assume that the body of the felt, as fOIl instance a felt hat, is first dyed a blue which dye should penetrate all the way through the body, or if not all the way through at least to an appreciable distance from the surface thereof. The surface is then dyed with a different color or shade as, for example, red with a print dye or dye that does not penetrate through the body or into the body to any appreciable extent, but merely dyes the surface of the felt closely adjacent the surface. Now when the surface is cut or broken into, the body color, the blue in the present instance, appears and mixes with the surface color, in the present instance the red, thus giving the changeable effects, such as opalescent for fluorescent effects. There is only a break ing of the surface with the print dye so that Application filed November 2, 1922. Serial No. teases.

the body color shows through and mixes with. the balance of the surface color. This cutting or breaking may be done by various means, such as sand paper, wire cards or heavy bristle brushes.

As mentioned above, various effects may be securec by varying the amount or depth of the cutting or breaking operation. In the present example if the cutting or breaking of the surface is very light the red will predominate; if it is carried deeper the amounts of the red and the blue may be made aboutequal; while if carried deeper the blue may be made to predominate. Other effects may be secured by superimposing two or more different shades or colors at the surface of the felt, so that when the surface is out or broken the plurality of colors or shades used will mingle with the body shade or color.

Still other and varied effects may be secured by dyeing different portions of the surface different shades or colors, or in different designs. In fact the different effects which may be secured by my process are unlimited. iny body color or shade can be used with any surface color or shade desired. After the surface has been cut or broken as described to give the mingling effect of the colors, the fur may be left loose on the surface giving the well known velour finish or it may be ironed to give a smooth surface. The process is also equally adapted to wool and fur felts.

it has been found in practice that very beautiful changeable effects are easily secured with this process, and that the varieties of these effects are unlimited. Also in the case of felt hats, the hat may be made to match almost any color or shade of trimming. Naturally the better and finer grade felts give better results than the cheaper or poorer felts, but the changeable effects are obtained with the cheaper grades though not as marked.

Having thus set forth the nature of my invention, what I claim is:

1. The process of treating felt which con sists in dyeing the felt a given color, then dyeng the surface another color, and then cutting or breaking the surface so that the colors mingle.

2. The process of treating felt which. con sists in dyeing the surface thereof a different color from that of the felt and cutting or breaking the surface so that the colors mingle.

3. The process of treating felt which consists in dyeing the felt with a penetrating dye, then dyeing its surface another color, and then cutting or breaking the surface so that the colors mingle.

4. The process of treating felt which consists in dyeing with a given color to a given depth from the surface, then dyeing the surface another color without its penesurface so that the different colors mingle.

trating the. felt to any a preciable extent, and cutting or breaking tie surface so that the colors mingle. I

5. The process of treating felt which consists in dyeing the body of the felt with a given color, then dyeing the surface thereof with a different color or shade in a desired design, and then cutting or breaking the In testimony whereof I affix my signature.
